The Red Phantom Tetra, scientifically named Hyphessobrycon sweglesi, is a vibrant and popular freshwater fish native to the clear waters of Colombia and Venezuela. Known for its striking coloration and peaceful temperament, it is a favorite among aquarium enthusiasts, especially those keen on community tanks.

Red Phantom Tetras are admired for their bright, iridescent red bodies, which are beautifully contrasted with a dark, almost black, vertical patch near the dorsal fin. Males are particularly colorful with more pronounced hues and typically display fuller, slightly elongated fins compared to females. The overall body of the Red Phantom Tetra is robust and slightly elongated, creating a lively flash of color as they move through the water.

In captivity, Red Phantom Tetras thrive in well-planted aquariums that provide ample space for schooling, as they are naturally gregarious and prefer the company of their own kind. A group of six or more is ideal to bring out their best colors and behaviors. These tetras do well in tanks that mimic their natural habitat, with soft, slightly acidic to neutral water, and plenty of hiding spots amongst plants.

The tank conditions should include a gentle flow and a variety of plant life, which not only adds to the aesthetic appeal but also helps to keep the fish comfortable and stress-free. It is important to maintain clean and stable water conditions to keep these tetras healthy, with regular water changes being a crucial part of their care.

The diet of the Red Phantom Tetra should be varied and nutritionally balanced to ensure they receive all necessary nutrients. It includes high-quality flake food, as well as frozen or live foods such as brine shrimp, daphnia, or bloodworms. This variety helps in enhancing their color and overall health.

Breeding Red Phantom Tetras can be a rewarding experience for aquarists. They are egg scatterers, typically spawning among fine-leaved plants. The water conditions for breeding should be slightly softer and more acidic than usual. After spawning, it is common practice to remove the adults to prevent them from eating the eggs.

Overall, Red Phantom Tetras are relatively easy to care for, making them suitable for both novice and experienced aquarists. Their vibrant appearance and peaceful nature make them an excellent addition to community tanks, where their dynamic swimming and schooling behaviors can be fully appreciated.
